This is a follow up article to a blog that my colleague, Guy Kyser wrote back in 2011 titled “Purple alert: Common Pokeweed”. Since that time, I probably get a dozen or so calls this time of year asking, “what is that huge weed growing in my yard with dark black berries and big green leaves.” Pokeweed!
I personally find this plant quite interesting. As a native to portions of the United States, it turns out this plant has a diverse history and in recent years it is being studied in cutting edge medical research and energy technology. Have I perked your interest? If so read on.

In late 2016 and early 2017, the Weed Science Society of America (WSSA) organized a series of seven "Herbicide Resistance Listening Sessions" around the country.
Brian Schutte (from New Mexico State University) and I co-hosted the Southwestern session in Tulare, CA on February 15, 2017 and, if you're a regular reader, this may sound vaguely familiar since I tried to drum up interest on the blog in November 2016 and Pratap shared

Glyphosate was commercialized in 1974. Since then, it has become one of the most widely used (and studied) herbicides. According to Duke (2018b), almost 20,000 scientific publications and patents have included glyphosate as a focus; only 2,4-D surpasses it with respect to citations. The articles in the 5th issue of the 74th volume of Pest Management Science all focus on glyphosate and arose from a day long symposium (which was also dedicated to the molecule) that was held at the 252nd annual meeting of the American Chemical Society (Duke 2018a).

It is well known that herbicide efficacy is strongly associated with environmental conditions (Kudsk and Kristensen, 1992), and this is why applicators are required (by law) to spray under specific environmental conditions. In recent years, we have witnessed an increase in extreme weather events that have emphasized the importance of maintaining proper environmental conditions at, but more importantly after herbicide application. As part of my PhD project, I demonstrated that the first 48 hours after treatment (HAT) with pinoxaden (Axial®,45 g L-1 EC, Syngenta, Switzerland) can have a major impact on the success of weed control (Matzrafi et al., 2016).
